unfortunately 02 would be the final year of it being remotely easy. Once 03 rolled around for class 2 data bus, subsequently 07 with CANBUS, The amount of work to properly utilize a cluster was increased immensely because of the built in assumption it will communicate with various modules and relay to other modules when its the data pathway. im sure there would be a lot of work to get controls or warning lights to work in the traditional way. the reason for the changing eliminated a LOT of wiring needed to convey the same or more information and to allow scan tool diagnostics and the ability to program modules/update, etc.
If someone has done it with 03+ or some company made a module set, I commend their dedication. Im not a huge nut for wiring / its not my comfort zone so id never step near a project like that
hopefully considering trucks were made bare bones for fleet options that gm kept the interconnectivity to a minimum.
If you were to attempt this on my 99 buicks cluster, rest in peace. 97 buick phased class 2 into the flagship(park avenue), 98 the century, and 2000 the lesabre. and if a single module wasnt present it would screw up everything in the car because they rely on eachother for relaying information and processing as a group of computers rather than individual computers with wiring to every sensor to eachother and to displays(IP).
Dont ask why I know all this, I watched a lot of boring technical information researching for my park avenue on some repairs. Curse of a brain thats an information sponge LOL
Fun fact, buick eliminated over 10 pounds of wiring from Park Avenue just from 99 to 2000 with mid generation improvements and streamlined pathways.
Once all cars in the US switched to CANBUS it became a lot easier to make universal tools or learning of how to work with electrical systems because it wasnt just a GM only thing(Like class 2) but something all auto makers phased in and has a similar roots kind of understanding.
